<p>When do you usually move on to advanced sat prep books like Barrons2400 etc…Like what score should I have when I move on to these books. THX!</p>
<p>Let me revise that…what score should one have before they use these. Also, can I just study from an advanced book directly or is it recommended that one study from a normal sat book first.</p>
<p>At least 1350 CR/M</p>
